Quiz Answer Key and Fun Facts

1. One million, or ten to the sixth power: According to the IEC, which of the following ISN'T equivalent to one million?

Answer: The number of bytes in a mebibyte

As the need for greater and greater information storage increases in today's society, a discrepancy arose over the definition of a megabyte. Some insisted that a megabyte was equal to 2 raised to the 20th bytes, whereas others used 10 raised to the 6th.

In December 1998, the IEC, or International Electrotechnical Commission, defined a new unit, called the mebibyte. The mebibyte is equal to 2^20 bytes, and the megabyte became 10^6.

2. 6.02*10^23, or Avogadro's Number, is a number that chemistry students have learned for years. What exactly does the number represent to chemistry?

Answer: The number of carbon atoms in 12 grams of carbon-12

A mole is the SI unit for amount of a substance, and Avogadro's number is a measure of how many atoms are needed to make a gram of a substance. Therefore, Avogadro's constant is one of the most important numbers in chemistry and in science. Chemists in North America even celebrate Mole Day on October 23(10/23)!

Answer: Carbon-14

Carbon-14, which has eight neutrons rather than six, takes 5730 years to decay halfway. Based on concentrations of that isotope, which is found in organic material, scientists can determine how long it has decayed and thus how old the discovery is.

4. What planet's mass is 5.972*10^24 kg? Here's a hint: it's the second largest of the ones listed below.

Answer: Earth

The mass of Venus is within the same order of magniture (10^24) as Earth's, but Earth still is heavier. Mars has a mass of 6.42*10^23, and Neptune has a mass of 1.02*10^26. Earth is also the densest planet in the Solar System, dwarfing Saturn, which has a density less than water's.

5. 3.0857*10^12 kilometers is equal to what unit, used extensively in astronomy? It's defined as "the distance at which one AU subtends one second of arc".

Answer: Parsec

Don't get confused: a parsec is equal to about 3.26 lightyears. A parsec is derived from a right triangle with one leg of length one AU. The angle opposite that leg measures one second, or 1/3600 degrees. The other leg of that right triangle is equal to a parsec.

In addition, a unit called the megaparsec (Mpc) is used to measure even greater astronomical distances. The distance between the Andromeda Galaxy and the Milky Way is 0.77 Mpc.

Answer: Pascal

The pascal is the SI unit for measuring pressure and is equivalent to one newton per square meter. Blaise Pascal, a Frenchman who worked extensively with barometers and air pressure, lends his name to this unit. A gauss measures magnetic field, and the other two don't have units named after them.

7. A curie is equal to 3.7*10^10 becquerels. What do these units measure?

Answer: Radioactivity

Named after the Frenchmen and woman who shared the 1903 Nobel Prize in physics, this unit measures radioactive distintegration. Gausses measure magnetic strength, coulombs measure electric charge, and electronegativity is measured by the Pauling Scale.

Answer: Young's modulus

Also known as the modulus of elasticity, the measure was named after Thomas Young, although Swiss mathematician Leonhard Euler was the developer of the original concept. Young's modulus measures pressure, and more elastic materials have a lower value on the scale.

9. At the time of writing in December, 2008, a certain Mersenne number was found to be almost thirteen million digits long and was equal to (2^243112609)-1. What was so special about this number?

Answer: It was prime

Mersenne primes are prime numbers that are equal to (2^n)-1, where n is prime. Unfortunately, not all prime numbers form Mersenne primes, so it has become a quest to discover which ones are prime. GIMPS, or the Great Internet Mersenne Prime Search, was started by George Woltman in 1996, and it has since held the record for the longest known primes discovered.

10. What name do we give to the number one, followed by 100 zeroes? A misspelling of this word led to the name of a company that is known worldwide.

Answer: Googol

While I won't attempt to write out that number here, suffice it to say that it is 10 to the hundredth power. In addition, a googolplex is the number 1 followed by a googol of zeroes!
